In this article, we will explore the concept of an Execution Management System (EMS) and its significance for the buy-side industry. We will delve into its features, benefits, and the key distinctions between an EMS and other related systems. By the end of this article, it’s our goal that you will have a clear understanding of what an EMS is and how it can enhance trading operations.
For full disclosure: Limina doesn’t provide an EMS, nor do we resell one. We have partners who do provide EMSs and we integrate with these partners. i.e. we’re completely independent when it comes to our clients’ EMS-selection.
Traders and their investment firms can greatly benefit from leveraging an EMS to streamline their trading activities, access real-time market data, and achieve faster and more efficient trade execution.
Read on to find out what Execution Management Software is and discover how it can aid your trading requirements.
What is an Execution Management System (EMS)?
An Execution Management System is essentially trading software for the buy side. It's a software platform that provides traders with real-time market data, advanced execution options, liquidity management tools, and transaction cost analysis. It enables traders to execute trades quickly and efficiently, optimising their trading strategies and improving overall execution quality while minimising trading costs.
Integration with Order Management Systems (OMS) allows for seamless workflow and improved operational efficiency.
EMSs are sometimes multi asset, but most commonly they tend to focus on one or a couple of asset classes. This is in part because trading capabilities differ vastly between instrument types.
Features of Execution Management Systems
An Execution Management System (EMS) is a software platform designed to execute trades quickly and efficiently. It provides traders with real-time market data, access to various trading venues, and advanced execution options. Here are some key features of an EMS:
Real-time Market Data
Execution Management Software offers traders access to in-depth, real-time market data. This includes information on prices, volumes, and liquidity across different trading venues. Having up-to-date market data allows traders to make informed decisions and react quickly to market movements.
EMSs provide traders with a range of execution options beyond simple market or limit orders. They offer advanced order types such as conditional orders, list trading, and multi-leg orders. These options help traders optimise their trade executions and improve their overall trading strategies.
An important feature of Execution Management Systems is their ability to centralise access to liquidity. Traders can view available liquidity across multiple trading venues and make informed decisions on where to execute trades. EMS also support slicing orders into smaller trade instructions across different venues to achieve better execution outcomes.
Transaction Cost Analysis (TCA)
EMS sometimes include tools for analysing the costs associated with trade execution. TCA functionality allows traders to evaluate the effectiveness of their trades, identify areas for improvement, and measure execution quality. This helps traders optimise their trading strategies and manage costs.
EMSs can be integrated with Order Management Systems (OMS) to provide seamless workflows in the front and middle office. If the capabilities are joined in one system, it is called an Order Execution Management System (OEMS). Integration allows for efficient order routing, trade allocation, and compliance checks. It enables traders to access relevant order information and see trade orders earlier directly in the OMS before they are sent to the EMS.
Other Systems Commonly Confused with Execution Management Systems
Various buy side trading technologies sometimes overlap and it can be challenging to distinguish between different systems and their specific roles. This confusion often arises when comparing an Execution Management System (EMS) to other related systems used in the Front Office, such as Order Management Systems (OMS) and Portfolio Management Systems (PMS). To clarify these distinctions, let's delve into each of these concepts. First, let’s illustrate the concepts:
An OMS serves as the central nervous system of investment workflows. It covers functionalities like rebalancing, order routing, and real-time portfolio analytics. OMSs primarily cater to front- and middle-office functions, enabling investment managers to streamline daily investment workflows, automate allocations, ensure compliance, and enhance order planning. While OMSs may offer execution capabilities, they are primarily used by portfolio managers to manage portfolios and generate orders based on their investment strategies.
Portfolio Management Systems can mean two things for a buy-side firm. For a hedge fund, a PMS enable tracking and management of positions, NAV, share classes and more. These systems offer features like shadow accounting, corporate action processing, fee management and sometimes general ledger.
For an asset manager on the other hand, a PMS is a Front Office tool used by portfolio managers to construct their portfolios. Functionality can be broad including integrated optimisation models, fundamental data and more.
While OMSs, EMSs, and PMSs may have overlapping functionalities, they serve distinct roles and cater to different user groups within buy-side institutions. Understanding these differences is crucial when selecting the right system for your firm's specific needs. Read more in our blog comparing OMS, EMS and PMS.
In the next section, we will explore the benefits of Execution Management Systems (EMS) and how they can enhance trading activities and improve overall efficiency.
The Benefits of Execution Management Systems
Buy side trading software offer several benefits that make them essential tools for traders in the financial services industry. Here are some key advantages of using an EMS:
Speed and Efficiency
Speed is crucial in today's fast-paced financial markets. EMS platforms provide traders with real-time market data and quick access to various trading venues. This allows them to make informed decisions and execute trades rapidly, helping traders achieve best execution and minimise slippage.
Better Execution through Market Insights
EMS platforms provide traders with in-depth market insights, including real-time data, charts, and transaction cost analysis (TCA). These tools help traders analyse market trends, monitor trade performance, and assess the impact of their trades on transaction costs.
Customisation and Flexibility
Modern execution platforms are highly configurable and can be tailored to meet the specific needs of traders and their trading strategies. Traders can customise their trading screens, set up personalised workflows, and define their preferred trading parameters.
Compliance and Portfolio Risk Software
EMS platforms often include trading restriction rule checks and monitoring, that help traders adhere to regulatory requirements and internal trading guidelines. Real-time compliance checks and pre-trade risk controls help mitigate the risk of trading errors and ensure regulatory compliance.
Execution Management Systems (EMS) provide traders with speed, efficiency, access to liquidity, advanced order types, market insights, integration with OMS (or jointly as Order Execution Management Software), customisation options, and compliance support. These benefits enable traders to execute trades effectively, make informed decisions, and navigate the complexities of the financial markets.
